Part Number: TPS54494 Tool/software: Hi,
I am working witha hardware which includes an ic from TI , and I am not able to identify it's variant , can you guys tell me which ic is this guy's :It's number is - "PS54494 1CTG4 A90S" , And for ps54494 there…
Part Number: TPS54494 Other Parts Discussed in Thread: TPS562242 , TPS564242 Tool/software: Hello,
I am going to use TPS54494PWP DC/DC converter on a board that will operate at an ambient/PCB temperature that can go slightly over 85°C.
I have a question…
Part Number: TPS54494 Hi,
We are having a strange issue in our application.
One of the load device in our application system connected from 1V8 on rail 2 is drawing very high current (it is getting hot beyond 100degC on the thermal pad). However we…
Part Number: TPS54494 Hi, All,
I have downloaded the TPS54494 PSpice transient model from the TI website, and created a component and a simulation circuit in LTspice, when the simulation circuit is running, the LTspice system shown "Too few nodes",…
Part Number: TPS54494 1. For VIN1 fed with a stable 5V input, who to connect VREG5, decoupling cap or 5V input?
2. Do you see issue converting from 5V to 3.3V? Any min On/Off timing issue, as 700KHz is pseudo-fixed?
Thansk..
Part Number: TPS54494 1. On page 13 of the datasheet, the VREG5 bypass is connected to PGND. On page 17 the layout example shows the bypass is to SGND. Which is correct?
2. Is there a tool to simulate and generate bode plot of the design with TPS54494…
Part Number: TPS54494 We are using TPS54494 on our design to generate four different rails 3.3V, 1.8V, 5V and 3.9V. In our design we are enabling all the buck by connecting it to 12V through a 10K pullup. The buck start turning on when the VIN raises…
Part Number: TPS54494 The input voltage range (4.5 V to 18 V) and output voltage range (0.76V to 7V) of the TPS54494 overlap. If an input voltage of 5V is provided, is the output voltage range 0.76V to 5V? Something different? I can't figure this out…

Hi,
I have recently got the TPS54494-EVM for the evaluation of the Dual Channel buck and got it working with little success. There are no discrete level alterations on the EVM board done. All tests are performed with Resistive…
Other Parts Discussed in Thread: TPS54494 Hello,
I am trying to use the TPS54494 IC as a dual 3.3V / 5V power supply - with little success. The output is mostly stable, but every 20-30ms the IC seems to "stop switching". I have attached an oscilliscope…
